In January, 1827, James Neville, an engineer of London, took out a patent for a "new-invented improved carriage," to be worked by steam, the chief object of which appears to have been to provide wheels adapted to take a firm hold of the ground. He proposed to make each of the spokes of the wheels by means of two rods of iron, coming nearly together at the nave, but diverging considerably apart to their other ends, where they were fastened to an iron felly-ring of the breadth of the tire, and this tire was to be so provided with numerous pointed studs about half an inch long as to stick into the ground to prevent the wheel from slipping round. A second method of preventing this effect was to fasten upon the tire a series of flat springing plates, each of them forming a tangent to the circumference, so that as the wheels rolled forward each plate should be bent against the tire and recover its tangential position as it left the ground in its revolution. It was considered that the increased bearing surface of the plate, and the resistance of its farthest edge, would infallibly prevent slipping. For propelling the carriage Neville proposed to use a horizontal vibrating cylinder to give motion direct to the crank axis by means of the compound motion of the piston rod, as invented by Trevithick, the motion to the running wheels to be communicated through gear of different velocities. T. S. HOLLAND Among the singular propositions for producing a locomotive action that were brought out early in the eighteenth century was that invented by T. S. Holland, of London, for which he took out a patent in December, 1827. The invention consisted in the application of an arrangement of levers, similar to that commonly known by the name of lazy-tongs, for the purpose of propelling carriages. The objects appeared to be to derive from the reciprocating motion of a short lever a considerable degree of speed, and to obtain an abutment against which the propellers should act horizontally, in the direction of the motion of the carriage, instead of obliquely to that motion, as is the case when carriages are impelled by levers striking the earth. JAMES NASMYTH Born in Edinburgh, Scotland, August 19, 1808. Died in South Kensington, England, May 6, 1890. While yet in his teens James Nasmyth showed great mechanical ability and constructed a small steam engine. In 1821, he became a student at the Edinburgh School of Arts. Six years later he had made a very substantial advance in his experiments. The story of what he endeavored to accomplish is best told by himself. In later life he wrote:
